Abstract: Abstract of the Disclosure This specification discloses a process for the production of petroleum from a petroleum-containing subterranean reservoir employing an aqueous driving fluid containing, as a thickening agent, a biopolymer.  The biopolymer is a heteropolysaccharide synthesized by an alga.  A particular biopolymer is one synthesized by the alga Porphyridium aerugineum.  The biopolymer may be employed in the aqueous driving fluid as an in-vivo solution or in a reconstituted form. There is also disclosed a process for the growth of, and synthesis of, biopolymer by an alga such as Porphyridium aerugineum.  In one aspect of this process, the culture for the synthesis of the biopolymer contains dissolved therein sodium nitrate in the amount of about 55 to 250 weight parts per million and a dium glycerophosphate in the amount of about 100 to 300 weight parts per million.  In another aspect of the process, the synthesis of the biopolymer is carried out under conditions of illumination of the culture such that three  radiant energy-related parameters are controlled, namely:  (a) the intrinsic slope of the initial segment of the cumulative absorbed radiant energy versus time curve, denoted ?a; (b) the cumulative moles of light quanta absorbed, denoted (Ea)c; and (c) the group formed by the ratio of (a) to (b), denoted .DELTA.. In a specific embodiment of the synthesis of biopolymer by Porphyridium aerugineum, ?a is about 0.33 Einstein (0.0165 kilowatt-hour) per liter of culture per day, (Ea)c is between about 1.2 to 2.0 Einsteins (0.06 to 0.10 kw-hr) per liter of culture, and the value of .DELTA. is about 0.18 per day.  In still another aspect of the process, the biopolymer is synthesized in two stages with manipulation of the three aforementioned radiant energy-related parameters, the culture in the first stage being subjected to artificial illumination for a period of time such that synthesis of the biopolymer begins and the culture in the second stage being subjected to diurnal natural illumination to continue alga growth and synthesis of the biopolymer.  In yet another aspect of the process, the growth of the alga and synthesis of the biopolymer is conducted under an illumination regime wherein the energy content of the illumination is enriched with respect to particular wavelengths.  In the synthesis of biopolymer by Porphyridium aerugineum, the energy content of the illumination is predominantly in the region of 600 to 700 nanometers.  There is also disclosed an upgrading of the biopolymer with respect to its thickening characteristics by complexing with a heavy metal or transitional metal ion such as trivalent chromium ion.  There is also disclosed a process wherein the biopolymer is synthesized at the site where the aqueous driving fluid containing the biopolymer as thickening agent is injected into the subterranean formation.

The lining of such a furnace usually consists of a material which closest to the furnace wall forms a layer of pulverulent material and which outside this layer consists of a layer of a very hard, almost infrangible outer mass. For such delining operation the invention suggests first removing material from the inner layer and then breaking up the outer layer in the regions where material from the inner layer has been removed. Thus, the hard outer layer is exposed and worked without any material from the inner layer in place as a support.

Abstract: ABSTRACT OF THE DISCLOSURE        The invention comprises a method of detecting the presence of a chemical component in an off-shore liquid such as sea water.  A stream of the liquid is subjected to passage there-through of a chemically inert carrier gas, whereby the chemical component contained in the stream, and any particulate matter associated therewith, is entrained by the gas.  The gas, en-trained component, and particulate material (if any) are removed from the liquid; and the particulate material is separated from the gas and chemical component.  The gas and chemical component are then passed into a plasma, and the light emitted therefrom spectroscopically examined.  The method has considerable ad-vantages over conventional techniques for the detection of chemicals in off-shore liquids, which have generally required the study of on-shore deposits.  Furthermore, the present invention is particularly useful in the detection of uranium and related minerals, whereas the prior-art techniques are ineffective for the detection of such materials under large bodies of liquid, such as sea water.

Abstract: ABSTRACT OF THE DISCLOSURE       This invention relates to an improved open ended package or container which is formed from a one piece blank to hold a pair of light bulbs in an end to end relationship.  The bulbs are spaced a desired distance from the open ends of the container and longi-tudinally retained in both directions as well as prevented from contacting each other in order to avoid breakage during shipping and storing.  The one piece cardboard blank is folded and secured by adhesive strips at each end to form a rectangular sleeve having a top, bottom, two sides, two open ends, and a partition element.         The partition element is provided with cut lines and fold lines to form two separating portions and two retaining portions, all of which extend across the container between the top and bottom, each in a different plane parallel to the two sides.  When the bulbs are inserted into the container, the two separating portions are resiliently laterally deformed and prevent contact between the bulbs as well as longitudinally retain each of them in one di-rection.  Each of the retaining portions extends across the con-tainer between the bulb portion of a bulb and a respective open end to longitudinally retain the bulb in the other direction.          The invention provides a very economical light bulb container which protects the light bulbs while at the same time leaving them open for inspection.
